I feel that I have to throw this out there. In the year 1257 AD Transylvania, Valahia, and Moldova. Were not really independent states, hungary or byzantine held sway throughout most of this time-frame. Also at this point in time Transylvania, Valahia, and Moldova were not that important to holding off the Turks, Byzantine still held Greece, Thrace, a large part of Anatolia, parts of the Balkans, and Macedonia. It would not be till the 1400s and 1500s AD that Transylvania, Valahia, Moldova, and the rest of the Balkan states really came into their own when it comes to defending against the Turks and being bonifide states.
This is from a strictly historical standpoint. I'm not trying to be insulting, or play on anyone feelings. Leave blatant nationalism out of it. Lets make a historically correct mod.
